FIELD: separation modules. SUBSTANCE: separation module of hollow fibres has an extended high-pressure casing and at least two sections of hollow fibre bundles. The ends of each section bundle are restrained in one pipe guard of the casing, on its each end. Fibres in each section are aligned so that filtrate in fibre passages flows along the trajectories passing from one pipe guard of the casing to the other. One or more impermeable barriers are formed in the casing for isolation of each section and control of passage of feed gas along the external surface of fibre bundles in countercurrent flow to filtrate motion in fibre passages. In the preferable variant of implementation ring fibre bundles are aligned around the central holder, passages are formed in the impermeable barrier for passage of feed gas from one section of fibre bundles to the other. Feed mixture that is subject to separation can be introduced in a point adjacent to the casing pipe guard, and raffinate is removed at the bundle end adjacent to the casing pipe guard, so the feed mixture flow and raffinate flow from each previous section move axially through bundles along the trajectory of flow in countercurrent flow of movement of filtrate through the fibre passages. Provision is made for means for recirculation of filtrate to feed mixture and passages of the first stage. EFFECT: improved design. 23 cl, 7 dwg
